Abstract

The invention relates to a design for air delivery device of an ultra-flat fuel cell engine, which comprises an electromotor, an impeller, a fan up-or-down drum, an inlet scoop and an outlet scoop. The central stator of electromotor is positioned on the fan up-or-down drum and the impeller is directly settled on the outer stator of the electromotor, which integrates the electromotor and the fan drum. The height of the whole air delivery device is the sum of fan up-or-down drum. The inlet scoop and the outlet scoop are equipped on the drum. Compared with the prior art, the design structure of the electromotor and drum integration is characterized in small volume and saving space. Besides, the performance of feeding wind is equal to the height of regular fan, and the impeller is directly positioned on the electromotor for self-heat-radiation when transferring wind.

Description

technical field [0001] The invention relates to a fuel cell, in particular to the design of an air conveying device for an ultra-flat fuel cell engine. Background technique [0002] An electrochemical fuel cell is a device that converts hydrogen and oxidants into electrical energy and reaction products. The internal core component of the device is the membrane electrode (Membrane Electrode Assembly, referred to as MEA). The membrane electrode (MEA) is composed of a proton exchange membrane and two porous conductive materials, such as carbon paper, sandwiched between the two sides of the membrane. On the two boundary surfaces of the membrane and the carbon paper, there are even and finely dispersed catalysts for initiating electrochemical reactions, such as metal platinum catalysts. Conductive objects can be used on both sides of the membrane electrode to draw the electrons generated during the electrochemical reaction through an external circuit to form a current loop. [...
